You can put this solution on YOUR website! if the sum of three consecutive odd integers is 237 then what are the integers
-----------------
1st: 2x-1
2nd: 2x+1
3rd: 2x+3
-----------
EQUATION:
2x-1 + 2x+1 + 2x+3 = 237
6x + 3 = 237
6x = 234
x = 39
-----------
1st: 2x-1 = 77
2nd: 79
3rd: 81

You can put this solution on YOUR website! hi, hope I can help,

if the sum of three consecutive odd integers is 237 then what are the integers
.
This is a pretty easy problem
First, you have to know the variables
.
consecutive means "in order" (example: 1, 2, 3, ... ) here is another example: (25, 26, 27, ... )
.
consecutive odd means "in order, but they have to be odd numbers" (examples: 3, 5, 7, 9, ... ) or ( 107, 109, 111, 113, ... )
.
Since this is our first number, we can name it "x"
.
Our second number would be "x+2" ( we have three consecutive odd integers ,meaning, if the first number is odd, you have to add 2 more to get the next odd number( example: let's say our "x" was 5, our second number would be "x+2", we replace "x" it will become "5+2" or "7", our first odd number is 5, our second is 7)
.
Our third number is "x+4" (if second number is odd, have to add 2 to get the third odd number
.
Your first number will always be "x"
.
If you are trying to find the consecutive numbers(not consecutive odd), you add 1 for each number ( first number = "x", second = "x+1", third = "x+2", fourth = "x + 3", ... )
.
If you are finding consecutive odd( or even) numbers, you add 2 for each number
( first number always = "x") ( first number = "x", second number = "x + 2", third number = "x + 4", fourth number = "x + 6", ... )
.
Since we are finding consecutive odd integers, our three numbers are( remember we start with "x" and add 2 each time)
.
First number = "x"
Second number = "x + 2"
Third number = "x + 4"
.
Since we know our three variables, we can know put them in a formula
.
if the sum of three consecutive odd integers is 237 then what are the integers
.
First number = "x"
Second number = "x + 2"
Third number = "x + 4"
.
Our fomula = 
.
Now all we need to do is solve for "x"
.
We can get rid of the parentheses, 
.
We will reorder the numbers, 
.
we will now combine like terms
.
 = 
.
we will now move "6" to the right side
.
 = 
.
We will divide each side by "3" to get "x"
.
 =  = 
.
We found that our first odd consecutive number(x) = 77
.
Our second number = "x + 2" ( replace "x" with 77) = "77 + 2" = 79
Our third number = "x + 4" ( replace "x" with 77) = "77 + 4" = 81
.
We can check by replacing "x" with 77 in our original equation
.
.
.
.
 ( True )
.
Our three numbers are
.
1st = 
.
2nd = 
.
3rd = 
.
Hope I helped, Levi
